The bacteria is a thermophile and is widely distributed in soil, hot springs, ocean sediment, and is a cause of spoilage in food products. It will grow within a temperature range of 30-75 degrees Celsius. Some strains are capable of oxidizing carbon monoxide aerobically.iological indicators are used in conjunction with chemical indicators and process indicators to validate sterilization processes. It was first described in 1920 as Bacillus stearothermophilus, but, together with Bacillus thermoglucosidasius, it was reclassified as a member of the genus Geobacillus in 2001.
Epidermidis and aureus are the species names of the two bacteria in the Genus: Staphylococcus. They cause the most common medical device mediated infections.Therefore, it is very important to understand their characteristics and the differences between them. The causativeness, drug resistance, virulent factors, and identifying characteristics are different between aureus and epidermidis. Staphylococcus Aureus.hey are common on skin as commensal bacteria, and in the nose as well. However, aureus is resistant to most of the antibiotics. The bacteria can produce enterotoxins, and these enzymes are the virulent factors cause a vast range of diseases.
